Sends a reset sequence to the specified peripheral card. The reset takes approximately 25 ms before the
peripheral card will once again execute the application. Allow 1.5 seconds after the reset has completed
before accessing the peripheral card. This function will check peripheral card information to determine
that the peripheral card is connected to a master.
PARAMETERS
handle
is an address index to device information. Use
rn_device()
or
rn_find()
to establish the
handle.
resettype
describes the type of reset.
0 = hard reset—equivalent to power-up. All logic is reset.
1 = soft reset—only the microprocessor logic is reset.
RETURN VALUE
The status byte from the previous command. -1 means that device information indicates the peripheral
card is not connected to the master.
Sets software watchdog timeout period. Call this function prior to enabling the software watchdog timer.
